viscosity. n, pl-ties. 1. the state or property of being viscous. 2. (General Physics) physics. a. the extent to which a fluid resists a tendency to flow. b. Also called: absolute viscosity a measure of this resistance, equal to the tangential stress on a liquid undergoing streamline flow divided by its velocity gradient. It is measured in newton seconds per metre squared.
Best Answer: Viscosity is the physical property used to determine a liquid's resistance to flow. Whether or not a liquid will flow quickly determines its viscosity. Think of spilling a glass of water on a flat surface. It disperses across the surface until there is no more water to disperse.
